That's still too much.  Last time I measured my K3, the drop was 0.6 V 
on TX at 100W.  Cartridge type [AGC] fuses and the holders are common 
culprits.  I've replaced all of my fuses with the automotive fuses with 
the blade type contacts.  They present a large contact area, are very 
tight, and have a large wipe as you insert and remove them.
